In the run-up to the bypolls, the Election Commission (EC) had transferred Khammam District Collector Lokesh Kumar, Superintendent of Police Shahnawaz Qasim and assistant returning officer Ganesh after the Congress complained against them.

The counting of votes will be on May 19.

In 2014, Venkat Reddy had won the seat by defeating his nearest rival Swarna Kumari of the TDP by 21,863 votes.
